Attack-Flow Graph

Executive Summary

This vulnerability is due to insufficient policy enforcement in the Passwords feature of Google Chrome before version 151.0.7922.72. A remote attacker who already compromised the renderer process could exploit this to leak cross-origin data by tricking a user into visiting a crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 151.0.7922.72. To detect it, check your Chrome version by running chrome://version/ in the browser address bar. If your version is below 151.0.7922.72, the system is vulnerable. Update Chrome to the latest version to mitigate the risk.

Impact Analysis

If you use an affected version of Chrome, an attacker could steal sensitive data from other websites you visit, such as login credentials or personal information, even if those sites are from different origins.

Compliance Impact

This vulnerability could potentially lead to unauthorized access to cross-origin data, which may result in data breaches. Such breaches could violate GDPR's data protection requirements or HIPAA's safeguards for protected health information, depending on the data exposed.

Mitigation Strategies
